This dessert—a fudgy, frozen or semifrozen chocolate mousse that's sometimes coated in ganache, then sliced—likely came from the 17th or 18th century, when royal pastry chefs lived large. I like to crumble in Speculoos cookies, like Biscoff brand, before freezing, to add crunch and pretty golden flecks, but anything that works with chocolate—from candied ginger to rum-soaked raisins—is fair game. It's at its best when semifrozen or thawed but still chilly.
